I think there is a lot of depth in HHGG. I read the whole 42 saga as a parable on society's tendency to trust computer outputs without understanding what they really mean. There's a lot of great social commentary in there, one example that springs to mind is a planet run by middle managers declaring leaves as fiat currency as that way money really does grow on trees. Eventually this leads to mass deforestation in an attempt to halt inflation. A good critique of the economic status quo about 20 years before such things were widespread.
